OPF PolyGranular contains an optimum level of sulpur. This means that one application brings all required key minerals. Calcium and potassium (K) in the mix are in sulphate form and easily absorbed. The nitrogen/sulphur ratio ensures a favourable amino acid profile in the crop. Efficiency of nitrogen is high due to the plant-based amino acids occurrence. Amino acids are less subjective to leaching in the soil profile. The chloride and salt content is low, eliminating the risk of damaging plants. The amino acids in OPF can be absorbed even at low temperatures.
Under normal conditions, approximately 50% of nitrogen is released within 4 weeks. The release of sulphur is spread over 50 days. Most effective fertilizers feed both soil and plants. This combination of essential minerals, plant-based sugars and plant-based aminoacids in OPF PolyGranular nourishes the soil and the plant.
Dosages depends on the current conditions such as soil condition, climate, location, etc. Apply OPF PolyGranular under dry conditions and avoid remains of OPF PolyGranular on the leaves. Application of OPF PolyGranular on the leaves, can cause burns in sensitive crops.
OPF PolyGranular should be distributed by a fertilizer spreader. For further information, please refer to the spreading chart (downloadable on this page).
